CDI Electronics Outboard Ignition Troubleshooting Guide

20 TROUBLESHOOTING GUIDE - Chrysler/Force Troubleshooting Chrysler/Force Troubleshooting COILS ONLY HAVE SPARK WITH SPARK PLUGS OUT: Check for dragging starter or low battery causing slow cranking speed. DVA test stator and trigger. MISS AT ANY RPM: 1. Disconnect the rectifier from the stator and retest. If the miss clears, replace the rectifier. 2. In the water or on a Dynameters, check the DVA output from the power pack outputs while connected to the ignition coils. You should have a reading of at least 150V DVA or more, increasing with engine RPM until it reaches 300-400V DVA maximum. A sharp drop in DVA right before the miss becomes apparent on all cylinders will normally be caused by a bad stator. A sharp drop in DVA on less than all cylinders will normally be the switch box or trigger. 3. Connect an inductive tachometer to each cylinder in turn and try to isolate the problem. A high variance in RPM on one cylinder usually indicates a problem in the switch box or ignition coil. Occasionally a trigger will cause this same problem. Check the trigger DVA voltage (see NO SPARK ON ANY CYLINDER above). 4. Perform a high-speed shutdown and read the spark plugs. Check for water. A crack in the block can cause a miss at high speed when the water pressure gets high, but a normal shutdown will mask the problem. 5. Check the triggering and charge coil flywheel magnets for cracked, broken and loose magnets.
